I have a friend who had financial problems and needed my help occasionally.

He was in his final year in University while I was in my third year. He needed some money for school fees and other academic purposes, and he came to me. Being a student， ______，but I gave him what he needed on the agreement that he would pay back. I didn’t bother him after that. I never asked when he’d pay back.

Later on，after he finished school，he got into another period of deep financial stress and called me on the phone. He asked to borrow some more money，promising that he’d pay all of it back once he landed a job. Out of kindness，I still gave him the exact amount he needed，which was twice the amount I had given him initially. He was so grateful. It’s so hard to find someone willing to lend you that amount of money，even with interest.

Fast forward a few months later. One evening，I was feeling happy and love filled my heart. I felt like performing a special act of kindness. And then I thought，“Why not cancel my friend’s debt? Things are so difficult for him，you know? ”So I called him up and told him I had canceled his debt. He was shocked! He couldn’t believe it. He was so happy and later sent me a message of heart-felt gratitude.

Me too! And I felt grateful for his gratitude.

In life，it is the small but powerful actions of love that matter. When life is over，that’s what counts.
